The enÂ·CORE 100i utilizes a new dynamic capsule with a custom-tuned diaphragm designed specifically to provide a tighter polar pattern perfect for miking instruments and other sources requiring high isolation. A custom circuit with transformer optimizes frequency response for use with drums and amplified instruments and vocals, while a specially-designed grille provides protection from instrument strikes and facilitates mounting in tight spaces, making the enÂ·CORE 100i a versatile addition to the enÂ·CORE family.
